Dave Roberts suspects yes:
I suspect there are many, many medium chillers who would be happy working 30-hour weeks and trading the extra income for leisure time. Or perhaps they'd like to share a job. Or maybe they'd like to work more when they need money and less when they don't — just "work and get paid for it" when they need to. Those options aren't workable for most people today because of the specter of health insurance. To deviate from the 40-hour employee model is to take on risk beyond what all but a few brave souls are willing to bear.
Similarly, there are all sorts of people who might like to be "killers" and start their own business or invent something new but are inhibited from taking the leap by the fear of losing or not being able to afford health insurance. Plenty of people take that chance, of course, but how many more would there be if that risk were taken out of the equation?
